Baking a batch of these on a rainy Sunday afternoon was one of those kitchen moments I didn’t expect to love as much as I did. Each square of this classic homemade Lamington cake recipe comes out with a feather-soft sponge center, a thin shell of dark chocolate glaze, and a generous coat of desiccated coconut that clings to every edge. Once you cut into one and see how clean the layers sit, it’s hard to stop at just two.
Why Lamingtons Always Win the Dessert Table
What makes this Australian lamington dessert so satisfying to bake is how the components work against each other in the best way. The sponge itself is deliberately plain and slightly dry, which sounds like a flaw until you realize it’s engineered to soak up the chocolate coating without turning soggy.
Rolling each cube through warm glaze and then into coconut gives you that signature bite: a faintly crisp exterior giving way to a soft, lightly chocolatey center. After testing several batches, I found that chilling the sponge overnight before dipping makes the whole process cleaner and less messy.
Everything That Goes Into the Batter
Here’s what you need to make lamington cake with coconut and chocolate from scratch. Nothing unusual, but a few details are worth paying attention to before you start measuring.
For the sponge:
- 4 large eggs, room temperature — cold eggs don’t incorporate as much air; pull them out 30 minutes early
- 3/4 cup (150g) caster sugar — finer than regular white sugar, it dissolves faster into the egg foam
- 1 cup (125g) all-purpose flour, sifted — sift twice if you want the lightest possible crumb
- 1/4 cup (30g) cornstarch — this is the texture secret; it keeps the crumb tender without making it dense
- 1 tsp baking powder
- 2 tbsp (30g) unsalted butter, melted and cooled — adds just enough richness without weighing down the foam
- 2 tbsp (30ml) warm milk
For the chocolate glaze:
- 2 cups (250g) powdered sugar, sifted
- 1/3 cup (35g) unsweetened cocoa powder — Dutch-process gives a deeper, less bitter color
- 1/2 cup (120ml) boiling water
- 1 tbsp (15g) unsalted butter
For coating:
- 3 cups (270g) desiccated coconut — finely shredded works better than coarse here; it sticks more evenly
Before You Start Baking
Grease and line a 9×13 inch (23x33cm) baking pan with parchment paper, letting the sides overhang slightly for easy lifting. Separate your eggs and bring them to room temperature. If you plan to make the easiest version of this easy lamington recipe for beginners, bake the sponge the day before — a fully chilled, slightly firmed sponge is dramatically easier to dip without crumbling.
How the Whole Thing Comes Together
Step 1: Whip the egg base
Beat eggs and caster sugar together with an electric mixer on high for 8 to 10 minutes until the mixture is very pale, thick, and holds a ribbon when the beaters are lifted. Rushing this step is the single most common reason a lamington sponge turns out flat and dense, so don’t cut corners here.
Step 2: Fold in the dry ingredients
Sift together the flour, cornstarch, and baking powder directly over the egg foam in three additions, folding gently with a large spatula each time. Use wide, deliberate strokes from the bottom of the bowl rather than stirring in circles. You want the batter to stay voluminous; it should still look airy and barely trail off the spatula in slow ribbons.
Step 3: Add butter and milk, then bake
Combine the melted butter and warm milk, then pour it down the side of the bowl before the final fold. Gently incorporate until just combined. Pour into the prepared pan and smooth the top. Bake at 350°F (175°C) for 22 to 25 minutes, until the top springs back when lightly pressed and the edges pull slightly from the sides. Cool completely in the pan, then refrigerate uncovered for at least 4 hours or overnight.
Step 4: Cut and prep the sponge
Lift the chilled sponge out of the pan and trim the edges if needed. Cut into 16 even squares, roughly 2 inches each. Work quickly and keep the squares cold while you prepare the glaze; warm sponge will drink up too much coating and start to fall apart.
Step 5: Make the chocolate glaze
Whisk sifted powdered sugar and cocoa powder together in a wide, shallow bowl. Pour in the boiling water and add the butter, whisking until completely smooth and glossy. Keep the bowl sitting over a pot of warm water while you dip, because the glaze thickens quickly as it cools and becomes difficult to coat evenly.
Step 6: Dip and roll
Using two forks, drop a sponge square into the warm glaze and turn gently to coat all sides. Lift it out, let excess glaze drip for a few seconds, then drop into a tray of desiccated coconut. Use clean hands or another fork to press coconut onto all sides before placing on a wire rack. Repeat with remaining squares. Let the finished lamingtons set at room temperature for 20 minutes before serving.
Serving Lamingtons the Way Australians Actually Eat Them
Traditionally, a classic lamington cake recipe needs nothing more alongside it than a strong cup of tea or flat white coffee. But there are a few ways I’ve served them at gatherings that always get noticed.
Lamingtons split and filled with jam: Slice each square horizontally through the middle and spread a thin layer of raspberry or strawberry jam inside before pressing back together. Some traditional versions also add a layer of whipped cream. It pushes them from afternoon snack into proper dessert territory.
Paired with whipped cream and fresh berries: Plate two or three squares alongside a spoonful of lightly sweetened cream and scattered raspberries. The sharp berry acidity cuts through the coconut coating in a way that makes the whole plate feel balanced.
Lamington Cake Variations Worth Trying
Jam-filled centers: After the sponge is baked and cooled, slice it horizontally, spread strawberry jam over the bottom half, and sandwich back before cutting into squares. It adds a fruity layer that works especially well when the glaze is slightly thinner.
Raspberry glaze swap: Replace the chocolate glaze entirely with a raspberry version made from freeze-dried raspberry powder, powdered sugar, and a splash of hot water. It turns the lamingtons bright pink, which children love.
Mix-Up Options When You’re Missing an Ingredient
Cake flour instead of all-purpose plus cornstarch: If you have cake flour on hand, you can swap the full-purpose flour and cornstarch combination for 1 and 1/3 cups of cake flour. The crumb will be slightly finer and even more delicate, which makes dipping a bit more challenging but the result is worth it.
Toasted coconut for a nuttier finish: Lightly toast the desiccated coconut in a dry pan over medium heat until it turns pale gold before rolling the squares. It adds a subtle roasted note that pairs especially well with the chocolate glaze.
Dairy-free glaze: Swap the butter in the glaze for refined coconut oil in equal measure, and use plant-based milk instead of water if you want a creamier coating. The texture difference is barely noticeable once the lamingtons are set.
How to Serve Lamingtons for Any Occasion
Knowing a few simple lamington cake storage and serving tips makes all the difference between a plate of sad, drying squares and ones that still taste freshly made the next day. I almost always make these a full day ahead because the coconut coating softens slightly overnight and the sponge settles into the glaze more completely.
- Afternoon tea spread — Arrange on a tiered cake stand alongside finger sandwiches and serve with strong black tea or a flat white for an easy Australian-themed spread
- Kids’ birthday table — Stack them in a pyramid and secure with toothpicks; the coconut coating keeps them from sticking together even in warm rooms
- Dessert platter — Slice each lamington diagonally and fan the halves out on a board with fresh strawberries and a small bowl of whipped cream alongside
- Gifting or bake sale — Wrap individual squares in squares of parchment and tie with twine; the coconut shell keeps them fresh and intact for transport
Getting the Texture Right Every Single Time
Sponge collapses after baking: Usually caused by underbaking or opening the oven door too early. Wait until the edges clearly pull from the pan sides and the center springs back firmly before removing. If a skewer comes out with wet batter, give it 3 more minutes.
Glaze falls off during dipping: Almost always a temperature problem. If the glaze has cooled below 104°F (40°C) it loses its flow and clumps. Keep it over a bowl of hot water and give it a quick whisk before each dip. Cold sponge squares also help the glaze stick cleanly rather than pooling at the base.
Coconut won’t adhere evenly: Let excess glaze drip for a full 3 to 5 seconds before dropping into the coconut. If the glaze is too thick, the coconut layer ends up lumpy and uneven; if it’s too thin, the coconut slides off. The right consistency coats a fork in a thin, even film without dripping continuously.
Leftover lamingtons keep well in an airtight container at room temperature for up to 2 days, or refrigerated for up to 4 days. I prefer them at room temperature; straight from the fridge the sponge can feel a little firm. If you want to prep ahead, the uncoated sponge freezes beautifully wrapped tightly for up to a month. Thaw completely in the fridge before dipping.

Instructions
Step 1: Preheat and prepare pan.
Preheat oven to 350°F (175°C). Grease a 9x13 inch (23x33cm) baking pan and line with parchment paper, leaving overhang on the long sides. Having the paper overhang ready saves significant time when lifting the cooled sponge out cleanly in one piece.
Step 2: Whip eggs and sugar.
In a large bowl, beat eggs and caster sugar on high speed for 8 to 10 minutes until the mixture is very pale, tripled in volume, and holds a thick ribbon for 3 seconds when the beaters are lifted. This foam is the entire structure of the sponge, so full volume here is non-negotiable.
Step 3: Fold in flour mixture.
Sift together the all-purpose flour, cornstarch, and baking powder. Add to the egg foam in three batches, folding with a wide spatula using slow, deliberate strokes from the bottom of the bowl. Stop folding the moment no dry streaks remain; overworking deflates the batter quickly.
Step 4: Add butter and milk, then bake.
Combine melted butter and warm milk and pour gently down the side of the bowl, folding until just incorporated. Pour into the prepared pan, smooth the top, and bake for 22 to 25 minutes until the center springs back when pressed and edges pull slightly from the pan. Cool completely in the pan, then refrigerate uncovered for a minimum of 4 hours.
Step 5: Cut sponge and prepare glaze.
Lift the cold sponge out using the parchment overhang and trim the edges. Cut into 16 equal squares. To make the glaze, whisk together sifted powdered sugar, cocoa powder, boiling water, and butter until completely smooth and glossy. Place the bowl over a pot of warm water to keep the glaze fluid throughout the dipping process.
Step 6: Dip in chocolate glaze.
Using two forks, lower one sponge square at a time into the warm chocolate glaze, turning gently to coat all six sides. Lift out and hold briefly over the bowl for 3 to 5 seconds to let excess glaze drip off. Do not shake or press; just let gravity do the work for an even, smooth coat.
Step 7: Roll in coconut and set.
Drop the glazed square immediately into a tray of desiccated coconut and use a fork or clean fingers to press coconut firmly onto all sides, including the top and bottom. Transfer to a wire rack set over a baking sheet. Repeat with all squares and allow to set at room temperature for at least 20 minutes before serving.

Note
- Chilling the sponge overnight is strongly recommended. A warm or same-day sponge crumbles during dipping.
- If the glaze thickens too quickly, add boiling water 1 teaspoon at a time and whisk to loosen.
- Desiccated coconut is preferred over sweetened shredded coconut; sweetened coconut tends to clump and results in an overly sweet finish.
- Lamingtons can be stored in an airtight container at room temperature for 2 days or refrigerated for up to 4 days.
- Uncoated sponge can be frozen for up to 1 month. Thaw fully in the refrigerator before dipping.
